9.2 CGROM
When data is written to or read from the DDRAM, wrap-around occurs from the end of one
line to the start of the next line. When the display is shifted each line wraps around within
itself, independently of the others. Thus all lines are shifted and wrapped around together.
The address ranges and wrap-around operations for the various modes are shown in
Table
Table 7.
The Character Generator ROM (CGROM) contains 240 character patterns in a 5 × 8 dot
format from 8-bit character codes.
